Anaerobic digestion of dissolved, suspended and solid organics has rapidly evolved in the last decades, but nevertheless still faces several scientific unknowns. For treating wastewaters, a novel and highly performing new system has been introduced in the last decade, i.e., the upflow anaerobic sludge blanket system (UASB). This reactor concept requires anaerobic consortia to grow in a dense and eco-physiologically well organized way. The application of this bioprocess in worldwide wastewater treatment is indicated. Challenges for the next decade are: the design of adequate bio-supportive supplements for high-rate anaerobic reactors, the development of proper measurement and control equipment, the direct anaerobic treatment of domestic sewage in tropical countries, the combination of anaerobic wastewater treatment with N and P nutrient removal and finally the total reclamation of treated wastewater. |
